ENVELOP-FEEDER.

Application filed July 3, 1919.

To all whom t may concern Be it known that l, FRANK J. BURKLEY, acitizen of the "United States, residing` at OmahaE in the county ofDouglas and Sta-te of Nebraska, have invented certain new and usefulimprovements in Envelop-Feeders, of which thefollowing is aspecification, reference being had therein to the accompanying drawing,

The invention relates to feeders for feeding envelope to printingpresses, whereby the envelope are fed one at a time and are grasped bygrippers carried by the roller, said roller carrying each envelop to aprinting point where the envelops are printed.

A further object is to provide a feed er receptacle for envelope whichmay be adjusted to receive different sizes of envelops, also to providesaid receptacle with feeding means' whereby the envelops may be pickedfrom the receptacle one at a time by the gripping members carried by theroller.

A. further object is to provide means whereby the stack of envelope maybe inclined, thereby facilitating the feeding of the same.

Vith the above and other objects in view. the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed, without departing from the spirit of the invention.

In the drawings Figure l is a side elevation of the receptacle showingthe same supported above a printing roller.

Fig. 2 is a plan view of the device.

Fig. 3 is a sectional view through the receptacle and the upper portionof the feeding roller.

Referring to the drawings the numeral l designates a feed roller bymeans of which the envelops are fed and conveyed to the printing point7which may be located below the roller, and 2 the gripper carried by theroller. There may be as many grippers as desired and for purposes ofillustration only one gripper is shown.

Supported on bars 3 and 4, which are disposed above the roller is anenvelop receptacle 5, in which receptacle envelope are deposited asclearly shown in Fig. 3. The envelops having their flaps 6 downwardlydis- Specification of Letters Patent.

posed so that as the roller revolves in the direction of the arrow asaid flap will be engaged by the gripper 2 and convey-ed to the printingpoint.

Receptacle 5 comprises the sections 7 and 8, which sections are providedwith side and front walls 9 and l0, the side walls being adapted toengage the ends of the envelops and the walls 10 are adjacent the flapedge of the envelops. Talle 10 are provided with lugs ll, which aredisposed in longitudinal slots 1 2 or' the supporting oar 3. Supportingbar 4 is also provided with a longitudinal slot 13, which slot is atright angle to slots 11i in the bottoms l5 of the sections 7 and 8.Passing` through slots 14: and the slot 13 are bolts 16, by means ofwhich bolts, the sec tions may be adjusted closer together or fartherapart, thereby allowing the use of the same receptacle for differentsizes of envelops. During this adjustment the lugs ll will movelongitudinally in the slots l2. The forward edges of the bottoms l5 arecut away so that the gripper 2 may enter the bottom of the sections farenough so that said gripper will engage the edge of the envelop flaps.The side walls of the sections are provided with guide flanges, wherebythe stack of envelops will be prevented from becoming` twisted.

Secured to the bar i as at 19 and disposed between the edges of thebottoms l5 of the sections 7 and S is a forwardly extending feed finger21, the free end 22 of which terminates adjacent the lower end 28 of adownwardly extending spring arm 2e. Arm 24 exerts a binding action onthe edges of the envelops, thereby providing means whereby the envelopswill be choked and prevented from feeding too fast. Adjustablelongitudinally on the linger 2l, by means of a lock bolt 25 is atriangular shaped envelop feed 26, the apex end of said feed being`adapted to be disposed below one edge of the staclr of envelope, therebycausing the edge of the envelop remote from the flap edge to be elevatedso that the gripper may easily grasp the flap and pull the envelope fromthe receptacle at a point between the ends 22 and 23 of the finger 21and the spring arm 24. By the inward or outward. adjustment of themember 26, it will be seen that the inclination of the envelope may beincreased or diminished and the proper feeding of the envelope insured.It will also be seen that by the adjustable construction of thereceptacle, that it will be possible for the same to be adjusted toreceive different sizes of envelops.

The invention having been set forth, what is claimed as new and usefulis An envelop feeder for printing presses comprising a receptacle, saidreceptacle being formed in sections, each section being supported insuch a manner that they may be adjusted in relation to each for therecep tion of dierent sizes of envelops, the forward ends of saidsections having their bottoms cut away, a spring` feed finger disposedbetween the bottoms of each section, a downwardly extending spring feedfinger between the sections at their front ends, the ends of the feedlingers terminating adjacent each other, an inclined member disposed inthe bottom of the receptacle, means for adjusting said inclined memberfor increasing or diminishing the inclination of the envelops and agripper carried by said feed roller and so disposed as to enter the cutaway portions of the bottoms of the sections to grasp an envelop flapand withdraw the envelop from the receptacle between the adjacent endsof the spring fingers.

ln testimony whereof I hereunto aliiX my signature.

FRANK J. BURKLEY.
